1.3 Installation 

The weighing indicator should be sited in a location accuracy would not be degraded.   

Avoid extremes of temperature. 

Avoid  unstable  power  sources.  Do not use  near  large  users  of  electricity  such  as  welding  equipment  or  large 

motors. 

Verify the voltage showing on the label matches the voltage in your area.
